Interrelationship of Bacillus thuringiensis Berliner to diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidaae), and its primary parasitoid, Diadegma insulare Cress (Hymenoptera: Ichneumonidae)
… and its ability to develop resistance to Bacillus thuringiensis was evaluated. The field population of diamondback moths was found to be susceptible to B. thuringiensis. Selection pressure at 153 I.U. of B. thuringiensis endotoxin per ml for nine generations did not cause any significant …

Development of microbial control for lepidopteran pests of the corn ear
… and ecologically sound. The efficacy of three Bacillus thuringiensis Berliner (Bt) products and Anagrapha falcifera multiple nuclear polyhedrosis virus (AfMNPV) to control Helicoverpa zea (Boddie) was evaluated in the laboratory and in the field on corn. The virulence of the entomopathogens for …

Impact of the microbial pesticide Bacillus thruingiensis Berliner subsp. kurstaki on Hymenopterous parasites of the imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae)
Three formulations of Bacillus thuringiensis Berliner subsp. kurstaki (Dipel 4L, Dipel 2X, and ABG-6167) were compared with the synthetic pyrethroid perrnethrin ( common name Pounce 3. 2 EC) for insecticidal activity and impact upon parasitism of the imported cabbageworrn, Pieris rapae (L.) …

Western corn rootworm (Coleoptera: Chrysomelidae; Diabrotica virgifera virgifera LeConte) emergence and abundance in transgenic cornfields with structured and seed blend refuges
… larvae have been managed using transgenic Bt (Bacillus thuringiensis Berliner) corn hybrids expressing toxic Cry proteins (i.e., Cry3Bb1, Cry34Ab1/35Ab1, mCry3a) for a decade. To delay western corn rootworm resistance to Bt toxins, growers must plant a non-Bt “refuge” in each Bt cornfield. This …

Field-evolved resistance to Cry3Bb1 corn by the western corn rootworm: Investigations of resistance, emergence, node-injury ratings, and fitness
… (US EPA) approved the use of transgenic Bt (Bacillus thuringiensis Berliner) corn hybrids to manage the larvae of this billion dollar pest. Bt hybrids express various toxic Cry proteins (i.e., Cry3Bb1, Cry34Ab1/Cry35Ab1, mCry3A, eCry3.1Ab) which have proven to be valuable tools for protecting …
